Serial No. 299,480.

.This invention relates to new and useful improvements in phonographs or talking machines and has particular relation to so-called portable phonographs.

An object of the invention is to provide a portable 'or stow-away phonograph which phonograph whereinthe parts are compactly arranged in such a manner as to provide for the carrying of disc records of two diameters (10 and 12 inches) without in any Way increasing the dimensions of the phonograph cabinet or detracting from its appearance.

Yet another object is to provide a. portable phonograph with an improved sound amplifying arrangement constructed in such a manner that full volume is secured without increasing the usual dimensions of such a machine.

A more specific object is to provide a portable phonograph including a horn of more than the usual length and size, and including a cover arrangement which, when the cover is open, provides an enlarged bell portion for the horn, such bell portion forming a part of the amplifying system.

A further specific object of the invention is to provide a phonograph wherein the tone arm is mounted in a forward corner of the cabinet and wherein the horn extends from the corner in which the tone arm is mounted, across the front of the cabinetone wall of the horn curving and terminating adjacent the rear end of the cabinet opposite the entrance of the horn thereby providing a motor space; and in which the motor board'is cut away at its rear end to provide an exit for the horn, means being provided for directing the sound upwardly at this oint; and in which the cover includes a pivoted panel for providinga record space and in addition carries side wings which cooperate with this pivoted panel tov provide an exit or hell portion for the horn.

A further object is to provide a phonograph including a lid having side wings to assist in providing an extension for the horn and including means cooperatin with said side wings or one of them where y the said side Wings 01 said side wing forms an element of the lid support.

Yet another object is to provide a phonograph including a hinged lid and a panel mounted within the lid and providing a rec- 0rd compartment therein, the cover and panel being pivoted on the same axis and movable relatively.

having the characteristics indicated and in which the panel or its lower forward surface carries a-block for cooperation with a metal strip to make a tight joint at the panel hinge, whereby the sound from the horn must pass outwardly over the motor board.

A still further object is to provide a phono-- A further object is to provide a machine become more apparent as the description proceeds, the invention consists in said-novel fea tures of construction, combination and arrangement of parts, as will be hereafter more fully described and pointed out in the claims hereto appended.

While in the accompanying drawings, the invention is illustrated in detail, and will in the following specification be described in the same manner, it is to be understood that since various changes will readily suggest themselves, the description and drawings are not to be taken as limitations on the scope of the invention since these are purely for the purpose of illustration, and it is therefore to be understood that reference must be had tothe annexed claims for a definition of the limitations of the invention.

Fig. 4 is an enlarged sectional detail view showing the mounting for the lid and record carrying panel;

Fig. '5 is a horizontal sectional view through the record carrying panel, the leaf or flap for separating the records of different diameter being in operative position; and

Fig. 6 is an enlarged sectional view on the line 6-6 of Fig. 2.

Referring in detail to the drawings, the machine comprises a cabinet including a body 8 and a cover or lid 9, these parts being hinged together. Within the .body, and disposed slightly below the upper edge of the side walls thereof, is a partition or motor board 10 below which is disposed any motor 11 for driving any turn table 12, disposed on a spindle 13. A tone arm 14 is mounted in one forward corner of the body 8, on the board or partition 10, and is provided with a reproducer 15 for cooperation with a record, when the latter is disposed on the turn table 12.

At its rear end, the motor board 10 is cut away as at 16 and disposed beneath the motor board, and extending from front to rear thereof, is a horn or amplifier, 17 This amplifier has its entrance disposed immediately below the partition or motor board 10 and in communication with the discharge end of the tone arm 14. The entrance portion of the horn may be in the form of a casting 18 curving laterally of the cabinet as it curves downwardly, secured at the end of the horn 17 which is preferably made of metal. Horn 17 is shown as substantially rectangular in cross section and comprises four metal pieces secured together to form the top and bottom and side walls of'the horn. The casting 18 and the horn 17 may be secured together in any suitable .manner, as for example by means of bolts or screws 19 passing through the flanges 20.

As best shown in Fig. 2, one wall 21 of the horn, extends in an arc toward the side of the cabinet, and then proceeds rearwardly along said side until it abuts against the rear wall of the cabinet. The other wall 22 of the horn is also in the form of an arc, but is struck on a lesser radius, and extends over as shown at 23 toward the opposite side of the cabinet, from that against which the wall 21 of the horn is disposed, whereby at its rear end, the horn 17 is the width of the abinet. In addition to the sides 21 and 22, vom 17 comprises a top 24: and a. bottom 25, the top 24 stopping along the line 16 whereby it does not project beyond the edge of the motor board, and the bottom 25 extending to abut against the rear wall of the cabinet.

A strip 26 of any suitable material serves to clamp the edge of the top 24 securely against the motor board, whereby to prevent any vibration of this part. The same function is accomplished in connection with the bottom 25 through the medium of a block 27. T he ends of block 27 also secure the rear portions of sides 21 and 22 of the horn against vibrationj As clearly shown in Fig. 1, the outer face of block 27 is curred in such a manner that the sound passing rearwardly in the horn is directed upwardly through the opening provided when the rear edge of the motor board 10 is cut away.

This block. is securely held in place by any suitable means, as for example, screws 28, and bears against the rear edge of the bottom wall of the horn 25 whereby to prevent Vibration of the same. Attention is directed to the fact that in addition to the gradual increase in the lateral dimension of the horn as it extends rearwardly, the vertical dimension is also gradually increased for quite a distance rearwardly or until the maximum as defined by the under side of the board 10 and the upper side of the bottom portion of the cabinet is reached, from which point the upper and lower portions of the horn extend rearwardly in approximately parallel relation.

VV't-hin the lid 9 is a panel 29 for cooperation with the lid to provide a record carrying compartment. Lid 9 and panel 29 more about the same axis. To this end a plurality of separate hinges are provided and one leaf of each of the hinges is secured to the rear wall 30 of the cabinet, as by means of screws 31. The other leaf of some of the hinges is then secured to the lid as by means of screws 32. This forms the hinged mounting for the lid.

To the panel 29 as by means of screws 33 is rigidly secured a bracket 34 which extends along the rear upper surface of the panel and has a series of depending arms 35v'l1icl1 at their lower ends are bent to provide attaching lugs 36 secured to the other leaf of each of the other hinges, as by bolts 37. All of the hinge elements, that is the hinge elements for both the lid and the panel, operate about a single hinge pin or pintle 38.

As the sound is directed upwardly through the opening 16 it strikes against the panel 29 and is deflected forwardly over the motor board and turn table. To prevent leakage of sound at the hinge, a metal strip 39 is secured at the upper portion of the rear wall Ill) upwardly as at 40;

For the purpose of cooperating with the of, a block 41 is secured to the under side of the panel 29, preferably by the screw 33. The rear edge of the block 41 is arcuate, as shown at 42 and-slidingly abuts the arcuate surface 40 of the strip 39, to prevent lea'kage of sound at this point. It will of course be understood that if the panel is omitted a block 41 may becarried by the cover.

It will be obvious from the foregoing that the panel 29 has a function in the amplifyingarrangement in addition to providing a record carrier. A portion of this extension of the amplifier comprises side plates or wings 43 secured to the lid as by, screws 44 and extending downwardly in pockets 45 provided for that purpose in the side walls 46 and 47 It will be apparent upon an inspection of Fig. 1 that the panel 29 and the plates 43, together with the board 19 provide an extension of the amplifier.

' One of the plates 43 also performs as a portion of the lid or cover support. To this end,

the plate is provided with an opening 48 in which engages a portion of a latch 49 normally urged into active position by a spring :50 and including a finger piece 51 for disengaging it. Latch 49 operates about a pivot 52 and is mounted on a plate 53, the under side of which may be eiigaged by a toe or off-set portion 54 on the lower edge of one of the side plates or wings 43. Such engagement limits the upward movement of the lid and brings the notch or opening 48 in position for the entrance thereinof the latch 49, tosecure the lid in open position.

Secured along the edges of the panel 29 are a pair of rails 55 and disposed between the rear ends of these rails, is a cross piece 56, which, with the rails and panel defines a record compartment 57. The upper inner'cors ners of the rails 55 are cut away as at 58, and a. leaf 59- sets therein when the lid is closed. This leaf is hinged to the cross piece 56 as by means of a piece of fabrikoid or the like as shown in Fig. 1. When the lid is closed as shown in Fig. 3, the smaller diameter records occupy the-pocket 57, while records ofv larger diameter are disposed on the leaf 59 as shown at 60 in this figure.

It is to be noted that with this arrangement of, record compartment, the weight of the records on the panel 29 when the parts are in the position shown in Fig. 1, will be transmitted directly by the panel and by the lid to the hinge, and the weight is disposed near the hinge. This lessens any tendency to loosen oted to the lid as at 62 and has a slot 63 06- operating with a pin 64, wherebyto'limit movement of the panel 29 relative to the lid.

lid, a cross bar 65 is provided with a catch 66 for engagement with the catch plate 67 disposed 'on the end of the panel 29. strip 39 and particularly the portion 40 there- With this arrangement, the panel 29 has two operative positions in which it cooperates as a portion of the amplifier extension. One of these positions is that shown in Fig. 1, wherein it serves to direct the-sound outwardly over the turn table almost horizontally. In its other position, the panel is secured by the catch 66-and directs the sound outwardly over the turn table at a higher angle.

It is usual and preferable to cover the en tire machine, that is the body 8 and lid 9 with leather or imitation leather, as sug gested at 68. In addition, the top. and bottom of the machine are padded as at 69. The covering material for the body 8 is extended up and over the edges of the walls of the body, and has its edge disposed against the inner sides of these walls as shown at 70,,in Fig. 3. Strips 71, preferably of metal, are disposed about the inner edges of these walls and ex tend-above the same. These strips serve to secure the edges of the covering material and conceal such edges whereby it is not necessary that they be cut with any great preci sion. Further, since these strips extend above the upper edges of the walls, they telescope within the cover when it is closed and serve to support the'cover and limit any tend ency which it might have to move relative to the body. This prevents straining or loosening of the securing means for the hinges.

Cooperating latch means 72 and 73 may be provided on the body and cover respectively, for securing the cover in closed position, and a handle 74 may be provided for carrying the machine, when the latter is closed.
